Around $118,000 was spent on this video to promote the Melbourne Metro project before it was cancelled by the previous Coalition government. The video was obtained by Fairfax in November 2014 under Freedom of Information.

Engineers will have to partially dam the Yarra River opposite Federation Square, or immerse huge prefabricated concrete tubes into the river, to build the Melbourne Metro rail tunnel.

The complex engineering challenge of building the $11 billion rail tunnel has yet to be fully resolved, despite the Andrews government confirming the alignment the tunnel will take through the city – straight down the spine of Swanston Street.

Victoria’s Premier Daniel Andrews did not answer basic questions on Thursday morning about how the tunnel would be built beneath the river.
